GEO BON
Coordinates
• Collection, management, distribution
Facilitates
• New products and services
Scope
• Ecosystems, Species, Genes, Ecosystem services
1. How is biodiversity changing?
2. Why is it changing?
3. What are the impacts?
7
GEO BON Example Products
Trends in ecosystem services
Trends in species abundance
CC impact on compositional diversity
CC impact on PA representativeness
Indicators…on the state of biodiversity
What information is needed to create those products?
1. How is biodiversity changing?
2. Why is it changing?
3. What are the impacts?
8
Essential Biodiversity Variables
Key variables needed to
• Create those products
• Answer those questions
Primary measurements
Derived variables
1. How is biodiversity changing?
2. Why is it changing?
3. What are the impacts?
9
Why are EBVs Essential?
Provide inputs to products
Provide guidance to Observation System
• What to observe…
1. How is biodiversity changing?
2. Why is it changing?
3. What are the impacts?
10
Connection to Decadal Survey
Both provide guidance to the Observation System
Differ in scope
• Decadal Survey: NASA observations
• EBVs: All data sources, organization-neutral
1. How is biodiversity changing?
2. Why is it changing?
3. What are the impacts?

EBV Next Steps
Refine
• Outreach and buy-in
• Workshops, surveys…
• Complete list of EBVs
Establish protocol for peer review and updates
Would this group be interested in filling out
a survey?
